My overwhelming impression of this clip was that is was so tame and not really seductive at all. Our leading lady is singing "I wish you would come play with me" and although her voice is young and cute, there is not even a hint of sex appeal and seduction in her voice and even less in her movements. The men who are spotlighted in the number also don't play into her sex appeal. If the move had been made pre-code I think we would have seen a lot suggestive movement.
All my life I have continually come back to The Music Man. Growing up in Northern Iowa in the city that the musical is based on, The Music Man is required watching, but I took it farther than that. I've easily seen the film over 400 times. I love almost everything about it, but what keeps me coming back is the magnetism of Robert Preston's performance as Harold Hill. He's absolutely perfect and has really ruined the role for any imitators.
